[Bug 1798512] Re: [ppc64el] LVM+crypto on ppc64el points to an invalid crypto_source

initramfs hooks of cryptsetup got "smarter" and generate dev-mapper name as seen in d-i as the source device...
... which has wrong X/-partX naming for multipath devices
... thus partman-multipath, should rename multipath devices "for target" once partman is finally done, as otherwise at update-initramfs an invalid crypttab is generated and included in the initramfs irrespective of what /target/etc/fstab says.

** Changed in: partman-crypto (Ubuntu)
       Status: Incomplete => Fix Committed

   Using full disk encryption, on a multipath device (in this case FCP) ended up in trying to open/unlock a wrong DM device

  Spawning shell within the initramfs

  
  BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu4) built-in shell (ash)
  Enter 'help' for a list of built-in commands.

  (initramfs) grep -r mpatha3 *
  cryptroot/crypttab:mpatha3_crypt /dev/mapper/mpatha3 none luks,discard

  
  Boot reproducibly fails because it can't find /dev/mapper/mpatha3. This is expected, since after install the device is named mpatha-part3.

  We really need to standardize on the naming...
